- Adaptive anti - interference for high - frequency surface wave radar based on orthogonal loop whip antenna arrays
單極子交叉環(huán)天線陣的自適應抗干擾 - High frequency surface - wave radar ( hfswr ) utilizes the surface - wave mode of vertical polarization electromagnetic wave propagation over sea water to detect targets of ships and aircrafts at distance beyond the line of sight
高頻地波雷達( hfswr )依靠高頻垂直極化電磁波沿海洋表面繞射傳播的機理,實現(xiàn)對海面艦船目標和低空飛行目標的超視距探測。 - The study on single electron transportation induced by a high frequency surface acoustic wave ( saw ) has important influence on the base theory of physics , further development of semiconductor devices and the research of metrology
高頻表面聲波( saw )驅(qū)動下的單電子輸運問題的研究對物理學的基礎理論、半導體器件的進一步發(fā)展和計量學的研究具有重要意義。 - The results show that thinner radar absorbing coatings can strongly attenuate high frequency surface waves , while alternate using of thin radar absorbing coatings and thin radar absorbing coatings compounded by frequency selective surfaces can strongly attenuate wideband surface wave and it is possible that high performance balanced stealth of super wideband can be reached using the alternate radar absorbing coatings
實驗結果表明，低厚度的雷達吸波涂層就可以實現(xiàn)高頻表面波的強衰減吸收，而頻率選擇表面與低厚度雷達吸波涂層相結合的復合涂層與雷達吸波涂層共同交替使用可以實現(xiàn)寬頻段表面波的強衰減吸收，有望實現(xiàn)目標物體在寬頻段范圍內(nèi)的高性能均衡雷達隱身。 - This can increase efficiently the signal - noise ratio of seismic record , under the general situation , the signal - noise ratio of big scale is small , because low frequency surface wave in big scale is more serious , the correlate of signal is smaller , so weighting stack can press efficiently low frequency surface wave , comparative promote the percentage of the effectual signal in constructing the signal
這樣可以有效地提高重構后地震剖面的信噪比，一般情況下，大尺度的信噪比都較低，因為大尺度內(nèi)的低頻面波比較嚴重，信號相關性較小，這樣做加權可以有效地壓制低頻面波，相對地提升有效信號在重構信號中的百分比。 - It's difficult to see frequency surface in a sentence. 用frequency surface造句挺難的
